A few weeks ago, JC came into our recurrent class and gave us a brief update. Interestingly, one of the FIRST things he talked about was the A321s. He told us the company has NO plans to get rid of those aircraft next year and that they were staying. So, unless something changed in the last couple of weeks, the A321s are supposedly here to stay.
Most of the other posts here are pretty much in line with what he said (4 aircraft next year, flat growth, more frequencies). The "flat growth" thing isn't encouraging from a pilot standpoint.
